I've created further step. Now Misterhouse registers as normal Pluto devices and plays role of being parent device for his few internal devices. In this manner, MH devices can be controlled from Pluto (in below example this is not yet functional - need to parse incoming messages from Pluto) - that also displays their status (sensors, etc..)....

for this to work, you need to create Misterhouse device and add few generic non DCE devices as its children. Then you customize example below and put it in MH code directory (code is not pretty, but I hope understandable)....
